I think this is my favorite submission I've played so far! Your interpretation on "Staying Warm" is super unique. The little intro in the beginning is hilarious but also helps get the point across. I've never actually played Picross, so I was super lost at first. But once I did the tutorial a second time and finished the first two levels I started to get the hang of it. I'll be coming back to this one from time to time as a nice brain teaser.
Really well done!
